BD6071HFN

Datasheet White LED Driver with Synchronous Boost Converter and PWM Brightness Control for up to 3 LEDs in Series BD6071HFN ●General Description BD6071HFN is boost DC/DC converter possible to boost output voltage up to 14V (Max.) and drive the white LEDs at constant. It is possible that turning on white LED steadily by a series connection which has no current variation, and by a fast transient response with current mode. And, BD6071HFN is white LED driver IC with synchronous rectification. With synchronous rectification (no external schottky diode required) and small package, they can save mount space. ●Key Specifications  Operating power supply voltage range: 2.7V to 5.5V  Switching frequency: 1MHz(Typ.)  Quiescent Current: 0.1μA (Typ.)  Operating temperature range: -30°C to +85°C ●Package W(Typ.) x D(Typ.) x H(Max.) ●Features  Boost DC/DC converter  Adjustment of brightness by external PWM pulse  Possible to driving 3 LEDs  Soft start function  Synchronous rectification Boost DC/DC converter  No external schottky diode required  Output Open Short protect HSON8 2.90mm x 3.00mm x 0.60mm ●Applications This driver is applicable for various fields such as mobile phones, portable game machines, Inter-phone camera, audio player, portable DVD player, back light for printer display etc… and support light of the camera for the mobile phone, simple flash. And, these can use power supply for OEL. ●Typical Application Circuit VIN CIN 1μF L 22μH VIN SW BD6...
